To all whom t may concern. i

Be it known that I, PATRICK J. LYoNs, a citizen of the United States, residing at Phialdelphia, countyof Philadelphia, and j State of Pennsylvania, have invented a new .and useful Improvement in Railway-Track Constructions, of which the following is a .full, clear, and exact description, reference `.being hadto the accompanying drawings,

which form a part of this specification. a My invention` relatesto arailway track construction foruse incrossings, switches, frogs, mates, etc., etc., oneither steam or street railway lines, of such a character as to permit of the ready removal and` replacey ment of the parts receiving the greatest wear without interfering with or damaging other parts. r In ya crossing, for example, the point where thewheel-.angeways meet is subject to greater `wear than any other part ofthe Utrack, due to the jumping of the wheel over the'intersecting flangeway. `It .is customary to place a removable plateor center in the track at this point, in order to Vperhmitof renewal of the worn` portionwithout the necessity of renewing the entire i. crossing. a The devices for this purpose now in luse are found to have many defects,

principally that they arevery difficult to `remove and that theirremoval frequently results in irreparable damage to the entire crossing. The object -of my invention is to provide a `track construction having a removable center adaptedfor use in crossings, switches, etc., etc., which` may be made upin any shape and used atanyangle, ,r jvwhich will be positively held injposition, when placed and at the same .time may be r readily removed without possibility `of dame age to any other parts and with a minimum .H of time and labor. 1 .1 e e l ItV is also customary in the known coni i a fstructionsfto bind the center and linA some clases maintain `it in place with` soft metal,

poured after the center is placedy in the crossing. This operation is expensive, due

to the high price and excessive: requirements in the amount of metalused and rendersthe i. e e with wheel flange grooves Z, adapted to center-.difficult to remove. 1. e

`A` further object of my, invention is to provide track construction wherein the userof softwmetal is greatly reduced andin A' no way hinders the. removal.- the' center.

Fig. I isa plan view ofcrossing showing a modification of the` structure of Fig. 1.

Fig?. 8 is a cross section through line 8MS, Fig.

Fig. 9'is a perspective view of a removable center of modified construction.

,Fig. 10 is a transverse cross section of Fig. 7 i

. Referring more particularly to `lfigsimL-(,

therail`- sections a are `each held at one of their ends in the'casting @their other ends "being connectedV in any suitable manner` to the `line oftrackfnotshown/ The casting, having iiange grooves la alining withthe `grooves in the trackway, is provided `with `the chambers c and d for the reception of the inset or center4 e and its `depending porv tion f. The center e has its corners cutoif asat e. At one of the corners of the casting between the Vrail sections the vertical slot g is cut out andrextends the depth of the casting.` Spaced `from thetop ofthe casting .and opening into the slot g, thekey- 'way hextends on a horizontal plane diagonally into the casting, passing through the ,chamberV d. The sides Aof the slot g near their outer edge areprovided with vertical i `slots z'- which extenddownwardly to a point below Vthe bottom of the keyway `t, and profvide guides `for the wedge j which is provided on `one side with thelug p. a `The inset or center e, 4adapted to fit into .the chamber c, isprovided onfitssur'face a aline with the grooves 7c' inthe casting, the

opening m. adapted whenfthe 4center in lines, Fig. 2. vReferring to Figs. 7-10, which illustrate a modification of my invention adapted t0 a crossing: The casting s is provided ivith 'vv-heel flange grooves t andthe recessed chamber u the bottom of the chamber having' theupwardly `extending eyes 0.9 The casting is provided at both ends With the vertical 'slotsg, having slots z" in their sides, providingv guides for Wedges j `Which are provided With lugs 29', similar tothe slots' g and z' and wedge y', Fig. 3, and the horizontal keyvvays It extending between the v"cl'iainber u and the vertical slots g.

The inset or center y having Wheel flange grobves adapted to aline wvith the grooves t is provided with lopenings 2 eitending into fitsb'ody from both 'endsY and slots a in its bottom for the reception or the 'eyes 'e in the bottom of the chamber u. The keys n provided With the elongated slots, 0 are similar in construction to the key a, Fig. `5.

Referring again to Figs. le, in practice the manipulation of my device is as follows:

The `cha'n'ibers 0 and Z inthecasting are ,cleanedV out and the inset orl center e set in flu'sh 'vvith thepu'pper surface of the casting,

remaining apertures beingV 'and so that the opening m in its depending portion f is alined with the keyvvay h. The slot `0 in the key fn, is filled vvithV clay or other heat resisting subsance and clay is Vpassed into the vertical slot g.' The key is ,then passed into the keyway 7L, solid end first, leayng a portion of the slotted end pr'otrnding into the vertical slot g The vve'dgey' is inserted in the guide slots z' and driven down to maintainthe key in posiftion. A Babbitt metal is then pored into the 'casting through one of the apertures e', the v vpl'u ,fgefd v'vith clay, `the ,metal passes into the chambers 0 "and "ci, nlling anyint'erstices betvveen the center and casting, forms a bedgfor the cen ter by iilln'lgunderneath it, and fills in about the keyin theopening mand keyvvay n.

` No metal, hovvever, gets into the slot inthe out by theclay filling.

key n or in the vertical slot y, being lkept Thenetal inakes the casting, center and key solid and forms a` b'ond tor the passage of electricity 'thro'ngh the rails.

Up'onjthe cooling ofthe metal, tnegro's's- 1ingis' readyfor use, being held soli y i vdly in place b'y the key and nletalf 'casti1`1g, inset inserted in 'a recess in the casting,

When it is desired to remove the center, the Wedge j is driven out by a hammer tap Von the lugp, the point of the tool g is insertedin the slot g, and driven d own until it drives theclay ont ofthe slot o 1n the key, thepoint thea enters the slot o and, as the 1tool is driven farther down, it tends, due to trance of `Water and dirt vWhich, in time,

would get under the center and tend to raise it. The 'amount or soft metal used is greatly Vless than in the present constructions, `as it is only used tc solidly connect theV center and key With theA casting. Since themetal is positively prevented from entering the" slot y and the slot k in the'v key no metal need be 'cut out preparatory to removing the center',` which renders`;its removal"- easy and is saving of time and labor.-

The operation of thevmodific'ations shown in Figs. '7-10' is similar to thatabove described and it is thbnght will be readily understood.

' I do not vvi'sh to limit my invention to the modifications" shovn, as it `i"s`fequallyadapt" able to any other ty'pe ofgtracE-cnstru'ction, Where a removable parti'sused because of'cXcessive or for 'otherreason. y
